Hmm, this reminds me of the transparent HTTP proxy issue. I suspect
an HTTP proxy server is between your box and www.FreeBSD.org and it
had a cache of the former page and didn't for the latter.
If that is the situation, cvsweb.cgi may have to add a header field
"Pragma: no-cache" or "Expire: ..(soon).." for such proxies that cache
even a CGI output. (But that applies to most CGI programs...)
